How do you name haloalkanes and Haloarenes?

Nomenclature of Haloalkanes and Haloarenes

  1. Select the longest chain containing halogen atom.
  2. Follow least sum rule while giving number to the carbon containing X− atom.
  3. Indicating the position of other substitutes (if any) name the alkyl halide as haloalkane.

Which reaction is applicable for both haloalkanes and Haloarenes?

i) Finkelstein Reaction The last method of preparation of haloalkane and haloarene is halogen exchange reaction. In this reaction, an alkyl chloride or alkyl bromide reacts with sodium iodide in acetone to form alkyl iodides. The reaction is an equilibrium reaction so there is a possibility of forming other products.

How many types of reactions do haloalkanes have?

There are three different kinds of halogenoalkanes: Primary, secondary and tertiary.

What are Haloalkanes and Haloarenes?

Haloalkanes are hydrocarbons containing aliphatic alkane with one or more hydrogen atom/s replaced by halogens. Haloarenes are hydrocarbons containing aromatic alkane with one or more hydrogen atom/s replaced by halogens.

What are Haloarenes examples?

Methyl chloride and ethyl bromide etc. are examples of haloalkanes. Chlorobenzene, bromobenzene etc. are examples of haloarenes.

What is the general formula of haloalkanes?

The general formula of haloalkanes is CnH2n+1 X, where X is a halogen atom. They can also be represented as R-X, where R is an alkyl group. Some typical haloalkanes are CH3Cl, CH3Br, CH3CH2Br, etc.

What is the difference between Finkelstein and Swarts reaction?

The key difference between Finkelstein and Swarts reaction is that the end product of Finkelstein reaction is alkyl iodide whereas the end product of Swarts reaction is alkyl fluoride. The reactants for Swarts reaction are either alkyl chloride or alkyl bromide along with a fluorinating agent such as antimony fluoride.

What is the general formula of Haloarenes?

The general homologous formula followed by this class is CnH2n+1 X. They are further classified into mainly three types on the basis of the carbon atom to which the carbon bearing halogen (X) atom is bonded- primary, secondary, and tertiary.

When do Haloarenes react with sodium they are called?

Fittig Reaction: When haloarenes react with Sodium in presence of ether diphenyl is formed. This reaction is called Fittig reaction.

How are haloalkanes and Haloarenes used in chemistry?

CBSE Class 12 Chemistry Notes : Haloalkanes and Haloarenes 1 By Halogenation of Aromatic Hydrocarbons It is an electrophilic substitution reaction. 2 By Side Chain Halogenation (It involves free radical mechanism.) 3 From Benzene Diazonium Salt 4 From Phenol

Why are Haloarenes react slower than benzene rings?

Due to the above reasons, haloarenes are somewhat deactivated than normal benzene ring towards the electrophilic substitution reaction. Thus these reactions occur slowly and require more drastic conditions as compared to those in benzene.

What do you need to know about haloalkanes in Class 12?

Chemistry Notes for class 12 Chapter 10 Haloalkanes and Haloarenes The replacement of hydrogen atom(s) in hydrocarbon, aliphatic or aromatic, by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively.
